the (often annoying to others who don't share it) overly happy attitude of early birders - often associated with a great eagerness to call 7am committee meetings and to embark on sales-related shopping trips that mimic dawn raids on enemy encampments

"it's his earlybirditude i can't stand - he doesn't seem to realize that if i'm awake at 6am it's because i'm still up from the day before, not because i had a sudden urge to go running"

"only the most manic earlybirditude could make the shopping mall seem appealing the morning after thanksgiving"

Rising earlier than one would like due to both unrelenting back pain and rambunctious felines playing on the bed.

After many attempts to sleep despite the above, finally climbing out of bed to quickly locate coffee, food, and pain relievers, only to be shocked once again at the genius of night owls; thus I now have earlybirditude (great morning cheerfulness).
